Bidirectional Phase Separation Spinning Under Natural Drying to Prepare Aerogel Fibers for Thermal Insulation.

ABSTRACT: Aerogel fibers have emerged as a promising solution in thermal insulation. Yet, the current preparation methods pose challenges: they are either inefficient for continuous production or involve energy-intensive and time-consuming steps like freeze-drying or supercritical drying, thus restricting their practical utility. Here, a bidirectional phase separation spinning technique is introduced for continuous and rapid production (360 m h^-1) of aerogel fibers at any desired length. Importantly, fibers can be directly dried at room temperature, eliminating the need for energy-intensive freeze-drying or other additional steps, significantly reducing energy consumption and processing time. Aerogel fibers produced using this method exhibit remarkable properties: low density (0.18 g cm
